[PATCH v2 xserver 7/9] xwayland: Refactor cursor management into xwl_cursor
Peter Hutterer

Wed Feb 8 02:42:13 UTC 2017
From: Carlos Garnacho <carlosg at gnome.org>
This struct takes away the cursor info in xwl_seat, and has
an update function so we can share the frame handling code
across several xwl_cursors.
